What does not work at the time of commit: Cosmetic filtering does not work: The content scripts responsible for cosmetic filtering fail when trying to inject the stylesheets through document.adoptedStyleSheets, with the following error message: XrayWrapper denied access to property Symbol.iterator (reason: object is not safely Xrayable). See https://developer.mozilla.org/en-US/docs/Xray_vision for more information. ... css-declarative.js:106:8 A possible solution is to inject those content scripts in the MAIN world. However Firefox scripting API does not support MAIN world injection at the moment. Scriptlet-filtering does not work: Because scriptlet code needs to be injected in the MAIN world, and this is currently not supported by Firefox's scripting API, see https://bugzilla.mozilla.org/show_bug.cgi?id=1736575 There is no count badge on the toolbar icon in Firefox, as it currently does not support the `DNR.setExtensionActionOptions` method. Other than the above issues, it does appear uBO is blocking properly with no error reported in the dev console. The adoptedStyleSheets issue though is worrisome, as the cosmetic filtering content scripts were designed with ISOLATED world injection in mind. Being forced to inject in MAIN world (when available) make things a bit more complicated as uBO has to ensure it's global variables do not leak into the page. |

uBlock Origin (uBO)
BEWARE! uBO is (and has always been) COMPLETELY UNRELATED to the website ublock.org.
uBO is NOT an "ad blocker"; it is a wide-spectrum content blocker for Chromium and Firefox with CPU and memory efficiency as primary features. After a new installation, the default behavior of uBO is to block ads, trackers, and malware sites through EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO's filter lists.

General Information
uBO is NOT an "ad blocker"; it is a wide-spectrum content blocker. uBO blocks ads through the EasyList filter syntax and extends the syntax to work with custom rules and filters. Furthermore, the advanced mode allows uBO to work in default-deny mode, which will cause all 3rd-party network requests to be blocked by default unless allowed by the user.
It is important to note that using a blocker is NOT theft. Do not fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.
Ads, "unintrusive" or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO's primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical, involved means (such as uMatrix).
EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO's filter lists are default enabled when you install uBO. Many other lists are available to block trackers, analytics, and more. Hosts files are also supported.
Once you install uBO, you may easily unselect any preselected filter lists if you think uBO blocks too much. For reference, Adblock Plus installs with only EasyList, ABP filters, and Acceptable Ads enabled by default.
Installation
Chromium
Microsoft Edge Add-ons (Published by: Nicole Rolls)
uBO should be compatible with any Chromium-based browser.
Firefox / Firefox for Android
All Browsers
Do NOT use any other content blocker concurrently with uBO to benefit from its higher efficiency. uBO will perform as well as or better than most of the other popular ad blockers. Other blockers can prevent uBO's privacy or anti-blocker-defusing features from working correctly.
Do NOT use uBO along with other similarly-purposed blockers.

Free. Open-source. For users by users. No donations sought.
Without the preset filter lists, this extension is nothing. If you ever want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.
